I am planning on assembling my own "kit" if you will, thats why I am posting here. I plan on using the 99cc motor from harbor freight on my 21 speed bike. I will be welding a platform for it to sit on.
Then I will be removing the pedals and putting a jackshaft to connect the crankshaft on the left side to the existing gears on the right side.
I will be using a centrifugal clutch off of the motor to get me going (along with a quick kick) so this will allow the motor to idle when stopped and get me up to speed when I put the throttle on.
My question for you all is: would the gears be able to withstand having a motor on it? I have heard of shift kits, but I really dont know what those even do. They just say it allows you to shift. But cant I do that in the first place if I'm using a jackshaft? And since I will be eliminating the pedals, and running the jackshaft from the opposite side of the 3 main sprockets, won't I be able to use my gears as usual?
Sorry for the long winded question. Your help is greatly appreciated.
